Capture context wherever you work

Second Brain isn't locked to one app or workflow. Pipe in notes from your terminal, browser, vault, phone, or any AI client that speaks MCP - it all lands in the same searchable memory.

capture on the go

Wherever the thought happens

Save context the moment it crosses your mind - mid-walk, mid-browse, or mid-read - without breaking stride to open an app.

build your own

Wire it into anything else

The same memory layer is open underneath - talk to it directly over HTTP, or hand the URL to any AI client that speaks MCP.

HTTP · JSON
REST API

Talk to your brain directly over HTTP. Build your own integrations, automations, or scripts on top of the same remember/recall endpoints that power every official client.

REST API vs. MCP - which one? Use the REST API when you're writing your own scripts, automations, or backend integrations. Use MCP when you want an AI client (Claude, Cursor, etc.) to read and write memory on its own during a conversation.
  1. Grab your Worker URL and auth token from the dashboard
  2. POST to /remember and GET from /recall with a bearer token
  3. Script it, schedule it, or wire it into any webhook you already run
# remember something
curl -X POST $WORKER_URL/remember \
  -H "Authorization: Bearer $TOKEN" \
  -d '{"content": "shipped v1.5"}'
 
curl $WORKER_URL/recall?q=launch+plan
